Hey all

I’ve just loaded up my Proxmark3 and encountered the attached error, hoping someone can help?

If on windows, can you open up device manager, ( or equivilant on other OS’s) and see if your PC can “see” your proxmark?

I have had tons of problems getting various Easy models to load rrg properly… it honestly takes a slog of different variations to get it working… I have two different Easy models both with 512k and both required slightly different approaches… one of these approaches tend to work; hold button down, power up, keep holding, run pm3-flash-bootrom, once finished, let go of button but let it flash lights and do whatever the heck it wants to do, see if com port comes back eventually, if com port app…
